    • A bearing unit includes a housing provided with a cylindrical bore and a linear bearing positioned within the cylindrical bore. The linear bearing includes a cage in which are arranged a plurality of endless ball rows each defined by a longitudinally extending ball track for load-bearing balls, a longitudinally extending return track for non-load-bearing balls, and deflection tracks connecting ends of the longitudinally extending ball track and the longitudinally extending return track. Each longitudinally extending ball track opens radially outwardly with a track plate being arranged to cover the longitudinally extending ball track for the load-bearing balls. The cylindrical bore of the housing is provided with a plurality of recesses each located in an area of the cylindrical bore facing one axial end of one of the track plates to permit radial deflection of the one axial end of the track plate.

    • A radial seal useful in linear ball bearings and designed to be secured during transportation as well as during operation of the bearing includes an arcuate disk portion having opposite sides. An arcuate projection is provided on each side of the disk portion, at least one of which is axially oriented. The projections are designed to have different diameters. This produces a stepped seating surface along the outside diameter of the radial seal that effects a reliable seating of the radial seal in the linear ball bearing. The radial seal can also be designed with two axially oriented projections disposed at different diameters on one side of the disk portion for projecting into an annular groove on the frontal face of the outer ring of the linear ball bearing. By constructing the projections with circumferential outer faces that slightly diverge in a cone-shaped manner, the projections further inhibit the seal from falling out of the groove.
    • 用于线性球轴承并被设计成在运输期间以及在轴承运行期间固定的径向密封件包括具有相对侧面的弓形盘部分。 在圆盘部分的每一侧上设有弧形突起,其中至少一个轴向定向。 突起被设计成具有不同的直径。 这沿着径向密封件的外径产生阶梯式的座面,其实现了径向密封件在直线球轴承中的可靠安置。 径向密封件还可以设计成具有两个轴向定向的突起,该突出部设置在盘部分的一侧上的不同直径处,用于突出到线性球轴承的外圈的前表面上的环形槽中。 通过以圆锥形的方式构造具有稍微发散的圆周外表面的突起,突起进一步禁止密封件从凹槽中脱落。

    • A ball bearing for permitting longitudinal movements with respect to a shaft includes a cage provided with at least two longitudinally extending guide tracks having opposite ends that are connected by semicircular turn around tracks. A plurality of balls are positioned in the guide tracks, with balls positioned in one of the guide tracks forming load-bearing balls and balls positioned in another one of the guide tracks forming non-load-bearing balls. The longitudinally extending guide track for the load-bearing balls is provided with a slit that is open radially inwardly for passage of the balls in a direction radially inwardly towards the shaft. The longitudinally extending guide track for the non-load-bearing balls has an interior wall which, in cross-section, possesses at least two substantially diametrically opposed first sections having a circular contour and at least two substantially diametrically opposed second sections laterally offset from the first sections and having a base that is set back from the circular contour.
    • 用于允许相对于轴的纵向移动的滚珠轴承包括设置有至少两个纵向延伸的引导轨道的保持架,该引导轨道具有通过围绕轨道的半圆形转弯连接的相对端部。 多个球定位在导轨中,其中一个导轨中的滚珠形成承载球和定位在另一个导轨中的球,形成非承载球。 用于承载球的纵向延伸的导轨设置有向径向向内开放的狭缝,用于使球沿径向向内朝向轴的方向通过。 用于非承载滚珠的纵向延伸的导轨具有内壁,其横截面具有至少两个具有圆形轮廓的基本上直径相对的第一部分,以及至少两个基本上直径相对的第二部分,其横向偏离 第一部分并且具有从圆形轮廓回退的基部。

    • A ball bearing for permitting linear movements includes a cage having an inner surface that is adapted to surround a shaft, a plurality of axial guide tracks for receiving load-bearing balls and axial return tracks for receiving non-load-bearing balls. A cover is provided at each end of the cage, with each cover being provided a turn-around track that connect an end of one guide track with an end of an adjoining return track. The guide tracks and the return tracks have a slit extending along the length of the tracks and opening radially inwardly. To enable economical production of the bearing with relatively simple tools and universal use of a single cage for different ball bearings, the lateral guide walls of both the guide tracks and the return tracks possess the same cross-sectional configuration and, in the radial outer area of the cage, are provided with axially extending grooves. The cage is manufactured with breaking points distributed around the outer circumference of the cage for permitting radially outer portions of the cage to be removed.
    • 用于允许线性运动的滚珠轴承包括具有适于围绕轴的内表面的保持架,用于接收承载滚珠的多个轴向导轨和用于接收非承载球的轴向返回轨道。 在保持架的每个端部处设置有盖,每个盖设置有将一个导轨的端部与相邻的返回轨道的端部连接的转向轨道。 引导轨道和返回轨道具有沿着轨道的长度延伸并且径向向内开口的狭缝。 为了能够以相对简单的工具经济地生产轴承,并且通常使用用于不同球轴承的单个保持架,两个导轨和返回轨道的横向引导壁具有相同的横截面构造,并且在径向外部区域 具有轴向延伸的凹槽。 制造保持架,其断裂点围绕保持架的外圆周分布,以允许保持架的径向外部部分被移除。
